Description
VB1
1
Base power supply for first stage amplifier.
RFIN
2, 3
RF input for the power amplifier. This pin is DC - shorted to
GND and AC - coupled to the transistor base of the first
stage.
VBIAS
4
VREF
5
Detector bias voltage supply.
Detector output voltage reference. Vout - VREF is useful for
tracking detector performance over temperature.
VOUT
6
VCC2
7
RFOUT
8, 9
Detector output voltage.
Collector power supply for second stage amplifier.
RF output for the power amplifier. This pin is DC - coupled
and requires a DC - blocking series capacitor.
VB2
10
Base power supply for second stage amplifier.
NC
11
Not connected.
VCC1
GND
12
Backside
Center
Metal
Collector power supply for first stage amplifier.
The center metal base of the QFN 3x3 package provides
both DC and RF ground as well as heat sink contact for the
power amplifier.
